深海稀土和多金属结核成矿理论研究

  该成果主要依托于中国大洋“十三五”资源环境类项目、中国地质调查二级项目和国家自然科学基金项目,重点实验室副主任何高文教高担任首席专家。项目聚焦水圈、生物圈、岩石圈等多圈层作用机制,坚持地球科学思想为指导,围绕太平洋深海沉积物、富钴结壳和多金属结核等深海矿产资源成矿理论这个重大基础地质问题,基于重点实验室多年调查研究样品和资料,开展了如下创新性研究:一是创新性地以稀土循环的角度讨论了深海稀土富集机制问题,在深海稀土元素超常富集机制研究方面取得重要突破;二是识别出不同多金属结核的物质组成和成矿环境,将水成型多金属结核划分成典型和非典型水成成因亚类,构建了多金属结核元素相关性知识图谱,揭示水成型多金属结核对海水金属元素选择性富集机制;三是以海水、孔隙水及生物磷灰石三大深海稀土赋存载体分析为基础,揭示了磷酸盐组分对深海沉积物稀土元素的贡献,系统建立了深海沉积物稀土成矿模型。在深海稀土、富钴型多金属结核、富钴结壳成矿理论方面取得诸多创新性成果,相关成果在《Science Advances》、《Geochimica et Cosmochimica Acta》、《Gondwana Research》、《Ore Geology Reviews》、《Journal of Geophysical Research: Oceans》等国际著名期刊发表多篇学术论文。
